1) What is Anodizing?

Anodizing is a process where a coating is built up on the surface of certain metals (titanium, niobium, tantalum, aluminum, magnesium and zinc) by heating, with chemicals, or by electricity. In the case of titanium, the coating that is built up is a layer of titanium dioxide. Titanium dioxide, which is also known as titanium oxide, occurs naturally on the surface of titanium. Anodizing the surface of titanium can be done by the use of heat but the results are not easily controlled. The most common method is to form an oxide layer on the surface with the use of electricity. The way that this is done is with a variable power supply in which an electrode is connected to the positive side (anode), and one to the negative side (cathode). Both are then submerged into a mildly conductive solution, thus completing the electrical circuit. The piece that is to be anodized is connected to the positive side, and that is why the process is called “anodizing”.

2) How are the different colors achieved?

Anodizing does not involve any dyes. The color on the surface is apparent because light reflects through the created oxide layer to create a color. Without the presence of light that color wouldn’t be there. Light reflects off of the surface of titanium. When a piece is high polished and not anodized, it reflects its mirror finish. When a piece is anodized, the light has to reflect [refract] off of the surface through the added oxide layer. The oxide layer filters the light waves passing through it and causes interference in the light reflected. This causes the light to reflect in a color. The color that is apparent on an anodized piece of titanium depends on the thickness of the oxide layer that has been applied to it. The thickness of the oxide layer that is formed during the process depends on the voltage of electricity that has been that has been applied to it. If you are anodizing more than one piece and you want them to be the exact same color, it would be a good idea to anodize them all at the same time. You may not get a color match if you do them on separate occasions. Thicker and/or larger pieces to be anodized may take longer and sometimes increased voltage, to achieve a similar color to their thinner, smaller counterparts.

3) What will you need to start anodizing?

  • An anodizer
  • A cathode (A sheet of non-corrosive metal like titanium or stainless steel. A scrap piece of Ti or SS that is larger than the piece being anodized will work, as well)
  • An anode ( The piece being anodized)
  • A submersion tank (This should be made of glass or plastic)
  • An electrolytic solution (TSP or a TSP-PF cleaning solution with water, baking soda with water, cola soft drink)
  • Electrodes

It is possible build your own anodizer. You can find information about this on the internet. It is much easier to buy an anodizer from a company that sells them already built. We get ours from Reactive Metals in Arizona. They come with the anodizer, electrodes, stainless steel cathode sheet, instructions, and a pamphlet with some info about anodizing.

The Anodizer your studio needs! The power to create scintillating colors, run larger baths and precise control. It is the right power supply for both one of a kind and production anodizing of body jewelry. Full digital voltage and amperage meters. 0 to 120 Volts. Extremely fine controls for more color options, and more precision. Anodizing titanium parts such as jewelry before sterilization and wear renders the surface smoother and passive. The anodization process removes microscopic particulate matter that would otherwise be missed by acid or alkaline cleaning, solvents, steam and ultrasonic methods. [*Reference - ASTM F-86 standard method for surface finish and passivation] This anodizer include two sets of color coded leads, one pair of rubber gloves, one stainless steel cathode and full instructions and support. In addition, Brian Skellie's body art specific instruction, tips and tricks gathered over two decades of experience to color and passivate titanium and niobium body jewelry with safe and artistic effects.

4) Which voltage achieves which color?

The more voltage that is applied during the process, the thicker the oxide layer that is achieved. The voltage range used in this type of anodizing is usually between 15-120V. The colors are in approximate ranges, and will differ slightly for each set up. It is good to start a little lower and turn it up gradually.

ColorCopperDark PurpleDark BlueLight BlueYellowFuchsiaBlurpleTealGreen
Voltage range8 to 10 V15 to 16 V18 to 20 V27 to 30 V48 to 50 V62 to 63 V72 to 75 (up to 79) V81 to 85 (up to 89) V91 to 92 (up to 95) V

This chart represents the voltage ranges that I use. I can usually achieve the color I am after within these ranges, however I always start out lower and work my way up. You can change the color of an anodized piece to another color of a higher voltage. It is possible, for instance, to turn a dark blue anodized piece to light blue, yellow, or to any of the colors of a higher voltage. It is not possible, however, to turn that dark blue piece to a purple or a copper color. If you wanted to do that, the oxide layer would have to be stripped off through polishing/steam cleaning. The quality and consistency of the oxide layer formed, largely depends on the quality of the surface finish. When we anodize a piece of jewelry to be sent out to a customer, we sometimes do not get the result we want on the first try. The piece then gets re-polished and steam cleaned, to be anodized a second time. It might be a really good idea, if you are planning to anodize jewelry yourself, to get a polishing wheel and a steam cleaner.

5) What are the benefits of an anodized surface?

6) Safety

  • NEVER touch the anode to the cathode when the power is on! This may cause your electrical circuit to short out, and may cause you to receive an electric shock. When your anodizer is not being used, shut the power off and put a cover over your submersion tank.
  • It would be a good idea for the anodizing station that you set up to be in a well ventilated area. Although it would be a very small amount, hydrogen gas is a byproduct of anodizing and can be explosive.
  • Because you are dealing with electricity, the use of rubber gloves is recommended.
  • Etching body jewelry is not recommended as it makes the surface rough.

8) Interesting Video

Scientastic demonstration with a strip of Ti about a minute in.

Scienterrific example of a very simple anodizing setup (interesting for one-off projects, not so good or precise for frequent studio use.)
